Saturday Teaser Curio #65: Picking Where to Buy

With Thanksgiving safely behind us, we turn our attention to twin "holidays" next up: Black Friday and Cyber Monday. When we have so many commercialized holidays (like Valentine's Day) already, there's something oddly comforting about having a straight-up, honest commercial holiday. But with so many sales, where do we BUY?

Below, several three-letter words are separated into three groups. All the words in a single group have a property in common, and no words in any of the other groups share that property. Where does the word BUY go and why?

TOE, RIG, SON, ONE

ACT, HOW, BET, DIM

BIG, EAT, POT, GAS

Ready for the answer?

In the first set, the letters in the words are in reverse alphabetical order. That is, T comes after O, which comes after E in the alphabet.

In the second set, the letters are in alphabetical order (e.g., A, then C, then T).
